2007 Mercedes-Benz CLS 63 AMG and CLK 63 AMG

Just a few weeks after the R63 AMG world-premiere and the ML63 North American debut at the Chicago show, the AMG crew is adding two more 6.2-liter-powered race horses to the stable, in the form of the CLS coupe/sedan and CLK coupe and convertible. The engine produces 514 hp in CLS form (the highest output of any naturally aspirated V-8 in the world) and 481 in CLK form. Both will use the same 7-speed automatic transmission spreading its work across the Mercedes-Benz line-up, and both will, of course, be clad with huge wheels and unique vents and body treatments.
